To all whom it may concern.-

Be it known that I, GIDnoN MARTEL, a citizen of the United States, residing at Chippewa Falls, in the county of Chippewa and State of Wisconsin, have invented anew and useful Threshing-ll/lachine, of 'which the following is a specification.

My invention relatesfto improvements in' threshing-machines; and the object that I have in viewis to provide a machine in which the grain may be rapidly separated from the straw and chaff and the grain winnowed and cleaned of refuse and chaff in a superior mangrain from the straw and chaff during its prog ress through the machine. Simultaneously with the treatment that the grain receives from the shaking-separator and conveyer mechanisms it is subjected to the blast from a fan in addition to the blast from the fan which is associated with the cleaning-shoe.

I have also provided a novel construction of the primary or upper shaking-separator and conveyer system arranged to carry the straw from front to rear of the machine and t0 effect the initial separation of the grain from the straw, and with this primary upper shaking-separator and conveyer system is associated a secondary intermediate conveyer arranged immediately below the primarysystem' and driven positively in a reverse direction to the line of travel of said upper system for the purpose of conveying-the grain from rear to front of the machine and delivering such grain to the third shaking-sepa rator and conveyer system, which also em-; bodies means for shaking and separating the; With this third and. lower conveyer system is combined the pri-:

chaff from the grain.

mary blower or fan, by which the chaff and fine straw are separated from the grain, and

said lower conveyer system delivers the grain directly to the cleaning-shoe, by which the grain is finally cleaned through the action of the sieves therein and the blast-fan associ-,

ated with said shoe.- This cleaning-shoe is mounted in the easing-or frame of the. ma-

guiding and reciprocating said shoe. is a vertical section of the straw-rack over the cleaning-shoe.

. chine to partake of an endwise reciprocating motion longitudinally'of the machine, and it is driven positively by connections with one of the rotary machine-shafts.

The several mechanisms are all operatively connected togetherto work in unison, and devices are-provided throughout the machine which prevent lodgment and entanglement of the straw or chaff with the working parts. The invention further consistsin the novel combination of elements and in the construction and arrangement of parts, which will be hereinafter fully described and claimed.

To enable others to understand my inven-v tion, I have illustrated the preferred embodiment thereof. in the accompanying drawings, forming a part of this specification, and in which- 1 Figure 1 is an elevation looking at one side of the improved threshing-machine with the frame or casing thereof skeletonized.

Fig. 11 is an enlarged fragmentary sectional view showing the rear end of the lowermost Fig. 10 is an enlarged fraginventionl have not deemed it necessary to particularly illustrate and describe the same.

As is usual in this art, I employ a toothed threshing-cylinder 2, situated transversely across the front end of the machine and having its shaft 2 journaled in suitable bearings on the machine-frame, said shaft having a driving-pulley 2, around which is passed a belt (not shown) for positively driving this threshing-cylinder. Beneath the toothed threshingcylinder is arranged the concave 3, which is suitably supported in the frame 1, and this concave has its rear end extended,

as at 4, to carry a series of transverse slats 5. These slats are spaced at suitable intervals from each other to provide openings between the same for the passage of grain to the vibrating straw board or rack, presently referred to, and with the slatted part of the concave is combined a rotary beater .6. This rotary beater lies in rear of and parallel to the threshing-cylinder. and extends transversely across the machine from side to side thereof, and the shaft 6 of this beater is j on rnaled on the machine-frame, one end of said shaft being extended beyond said frame or casing and equipped with a driving-p ulley 6 My invention contemplates the employment of an upper shaking-separator and conveyer system having its several parts arranged in inclined relation to each other to extend rearwardly from the threshing-cylinderand beater entirely through the machine to the rear delivery end thereof, and this up per shaking-separator and conveyer system serves to effect the initial separation of the grain from the straw and to carry the major portion of the strawlongitudinally through the machine and deliver the same to the stacker. This upper shaking-separator and conveyer system comprises in its entirety a number of working parts, and I will now proceed to describe in detail the several elements of said conveyer system. The first element of the upper conveyer system which I will describe is the vibrating straw board orrack 7. This straw board or rack 7 has its front receiving end situated below the threshing and beating cylinders, and it extends in an upwardly-inclined direction rearwardly to the first conveyer of the upper conveyer system. The vibrating straw board or rack 7 embodies a frame 7, carrying two series of transverse slats. The slats 8 at the lower front part of the cylinder are triangular in cross-section and assembled to have their edges abut against each other to impart a step-shaped appearance to the straw board or rack 7 from a point at the front end thereof to a point about or a little in rear of the center of said straw board or rack, thus forming an imperforate stepped section on the straw board or'rack which receives the grain and straw directly from the threshing and beating cylinders. The other series of slats 9 of this vibrating straw board or rack are triangular in'cross-section; but they are attached tothe frame of said board or rack to provide the spaces or slots 9 between themselves, and thus the upper delivery part of this straw board or rack has a series of openings separated by the spaced slats, whereby the rack is adapted to sustain the straw and chaff upon itself and permit the grain loosened from the straw to pass through the openings or slots upon the lower conveyer and in the path of the blast from the primary fan. The front end of the vibrating straw board or rack is hung beneath the threshingcylinder by means of the rock-shaft 11, which is suit-ably attached to the frame 7 of said board or rack and has its cranked ends 11 j ournaled in suitable bearings on the frame 1. The slotted rear part of the said straw board or rack is in like manner sustained by means of a rear rock-shaft 12, that extends across the machine and is suitably connected to the frame 7 of said board or rack, and the cranked ends 13 of said shaft 12 are journaled in bearings, also attached to the frame 1. This inclined vibrating straw board or rack is positively actuated by means of a crank-shaft 14, which is journaled on the frame 1 at a point between the rock-shafts 11 12, which suspend the straw board or rack within the machine, and this operating-shaft 14 is connected operatively with the straw-board by means of the arm 16, said arms being attached at one end to the sides of the straw board or rack and having their opposite ends fitted to the cranks of the shaft 14. At

one end this crank-shaft 14 for driving the straw board or rack is extended beyond the machine-casing, and to said extended end thereof is rigidly fastened the large drivingpulley 15 and the smaller pulley 122, adapted to drive the return tailings-elevator.

The front shaking-separator and conveyer of the upper conveyer system is indicated in its entirety at 18, and said front conveyer is arranged in an upwardly and rearwardly inclined position from the delivery end of the vibrating straw board or rack, the rear end of said front conveyer l8 lying in a horizontal plane considerably elevated above the rear delivery end of said inclined straw board or rack, while the frontreceiving end of said inclined front conveyer 1S liesbeneath and in close relation to said straw board or rack 7 to receive the straw and chaff having the grain mixed therewith directly from said board or rack 7. The front conveyer 18 is ISO driven positively by means of a shaft 19, which is journaled in suitable bearings 19, provided on the frame or casing 1. The frame 20 of this front conveyer is hung or loosely mounted on the driving-shaft 19, and the other or free end of this conveyer-frame 20 carries an idler-roller 21. The idler-roller is journaled loosely in the frame 20, at or near the lower part thereof, contiguous to the delivery end of the straw board or rack, and said idler-roller is parallel to the drivingshaft 19. The conveyer 18 consists of a pair of endless bands or chains passing around the idler-roller 21 and a driving-roller 19 on the-shaft 19, and to said endless bands or chains are attached the transverse slats 22, which are provided with the forwardly-inclined teeth 23 of suitable length to extend beyond the corrugated straw bars or rods 24. These straw bars or rods 24 are attached to and carried by the frame 20 of the front conveyer 18, and said straw bars or rods are arranged parallel to each other lengthwise of the conveyer and at a suitable distance above the same. Said bars or rods 24 are corrugated throughout their length to present an irregular working surface to the straw as it passes over the front conveyer 18, and the described construct-ion of said corrugated bars or rods serves to agitate the straw and chaff as they are carried along by the toothed bars of said endless conveyer, thereby serving to in a measure free the grain from the straw and chaff. The corrugated bars or rods are attached rigidly at their front ends to the front cross-rail of the conveyer-frame 20, and while the said rods or bars are attached near their rear ends to the rear cross-rail of said frame 20 said rods or bars do not terminate at said rear cross-rail, because they are extended or projected in a downwardly-inclined direction from the conveyer and its frame, thereby forming a series of deliveryfingers 25, that overhang the rear conveyer 27 of the upper conveyer system.

It will be observed that the frame 20 of the front inclined conveyer 18 is hung on the driving-shaft 19, thus allowing the lower front end of said conveyer-frame to move a limited distance vertically in the main frame or casing 1; but the descent of this frame and the conveyor thereon is limited by suitable stops, which are shown in the drawings as suitable blocks 20"; but the means for limiting the movement of said tiltable conveyerframe is not material, as the same may be changed at pleasure.

I prefer to have the front lower end of the inclined front conveyer 18 terminate at a short distance in rear of the slotted or open rear end of the straw board or rack 7, and the space between said straw board or rack and the front inclined conveyer 18 is closed against the passage of straw and chaff by means of a series of fingers 26, which are attachcd to and movable with the delivery end of the straw board or rack 7.

These fingers 26 are bent or corrugated throughout their length, and they are arranged parallel to each other transversely across the straw board or rack. The front ends of said corrugated or irregularly-for1ned fingers 26 are attached rigidly to the rack or board 7 in any suitable way, and said fingers project well over the conveyer 18; but they do not contact therewith, because they lie in a plane above said conveyer and its corrugated bars or rods 24. These fingers serve to catch the straw and chaff as they pass from the slotted board or rack 7 and to deliver the same to the conveyer 18 in a manner to effectually prevent the straw and chaff from passing to the intermediate return-conveyer, presently described, between the vibrating straw-board and the endless traveling conveyer 18.

The rear traveling conveyer 27, forming a part of the upper conveyer system, is similar in all substantial respects to the front shaking-separator and conveyer 18; but this rear conveyer 27 is arranged in such an inclined position that its rear delivery end terminates in substantially the same horizontal plane as the corresponding end of the front conveyer 18, while the front receiving end of said conveyer 27 is on a plane below the rear delivery end of the conveyer 18'. The rear conveyer consists of a pair of endless belts or chains which carry a series of transverse slats 31, rigidly attached to the belts or chains, and said slats or bars 31 have the forwardly-extending teeth 32. The rear endless conveyer 27 is mounted in a frame 29, the rear end of which is loosely hung on the driving-shaft 28, situated at the upper end of said conveyer 27, and said frame 29 carries the idlerrolier 30, which is suitably journaled in the lower front part of the frame, the belts or chains of said conveyer 27 passing around said idler-roller 30 and a driving-roller 28 on the driving-shaft 28. The frame 29 of this inclined rear conveyer 27 carries a series of corrugated bars 33 similar to the corrugated bars 24 of the front inclined conveyer 18, and the front ends of said corrugated bars 33 are attached rigidly to the front cross-rail of the frame 29, while the rear ends of said corrugated bars 33 are attached to the frame 29 and extended rearwardly therefrom to form the delivery-fingers 34. The teeth 32 of the rear endless conveyer 27 pass through the spaces between the corrugated bars 33, fixed on the con veyer-frame 29, and said corrugated bars serve in relation to the conveyer 27 the same purpose as the corrugated bars 24 serve to the conveyer 18that is to say, the bars 33 support the straw and chaff as they are carried by the conveyer 27 to the deliveryfingers 34. The space between the delivery end of the front shaking-separator and conveyer l8 and'the receiving end of the rear conveyer a7 is practically closed against the passage of straw and chaff by means of the series of detaininglingers 35, attached rigidly to the front cross-rail of the conveyen'frame 29 and extending upwardly toward the drivingroller of the front conveyer 18, and said lower front end of the conveyer-frame 29 carries a series of downwardly-curved guard-fingers 35, which extend beneath the conveyer 27 and lie adjacent to the intermediate longitudinal conveyer 50, said guard-fingers 35 serving to catch and detain any straw which may be lodged upon said conveyer 50, and thereby reduce to a minimum the return of straw and chaff by the conveyer 50 to the front end of the machine.

The shaft 19 of the front endless conveyer 18 is equipped at one end with a driving-pulley 36, adapted to be driven, in a manner presently described, from the counter-shaft that actuates the lower grain-board of the machine, and the other end of said shaft 19 has a belt-pulley 37, around which passes a belt 39, that extends to and around the belt-pulley 38 on the shaft 28 of the rear endless conveyer 27, whereby the shafts 19 28 of the two conveyers 18 27 are operatively connected together to have the rear conveyer 27 driven by the shaft of the front endless conveyer 17 The final element of the upper shakingseparator and conveyer system of my improved machine is the finger-shaft 40, which is arranged in rear of the driving-shaft 28 for the rear endless conveyor 27 said fingershaft being journaled in suitable bearings 41, attached to the frame or casing l on a plane below the shaft 28. This finger-shaft carries two series of fingers 42 43, which are suitably attached thereto. gers 42 are arranged to project beyond the front side of the finger-shaft and extend below the driving-shaft 28 of the inclined rear conveyer 27. The rear series of fingers 43 extend in inclined directions from the fingershaft 40, and the rear terminals of "said fingers 43 are adjacent to the rear delivery end of the second intermediate conveyer 50 of the threshing-machine. The fingers 34 at the rear delivery end of the rear endless conveyer 27 extend downwardly and over the fingen shaft 40, and thus the front series of fingers 42 of said shaft 40 and the rear delivery fingers 34 of the frame 29 for the endless c011- veyer 27 are arranged to overlap each other in a manner to effectually prevent the straw and chaff from passing down to the intermediate second conveyer 50 of the machine. This finger-shaft 40 is positively rocked or 05 cillated by connections with the operating parts of the machine for the purpose of vibrating the two series of fingers 42 43 thereon, and thereby give to the straw and chaff a vibrating or shaking motion to free the loose grain therefrom prior to its delivery from the machine, and in the preferred embodiment of the machine for rocking or oscillating this finger-shaft I employ an arm 44, a crank-disk 45, and a link 46. The crank-disk 45 is rigidly attached to one end of the shaft 28, that drives the rear endless conveyer 27, and to a suitable wrist-pin on this disk 45 is attached The series of fin the front end of the link 46. The arm 44 is rigidly attached to the finger-shaft 40, and to the upper end of this rocking arm 44 is pivotally connected the rear end of the link or pitman 46, thereby operatively connecting the finger-shaft 40 with the rear driving-shaft 28 of the rear endless conveyer 27.

From the foregoing description, taken in connection with the drawings, it will be seen that the conveyers 18 27 and the finger-shaft, which constitute elements of the upper shaking-separator and conveyor system of the threshing machine, are so constructed as to sustain the straw as it is moved by the conveyers and fingers through the machine, and at the same time the conveyers and fingers are constructed to permit of the passage through the same of any grain which is loosened from the straw or chaff by the agitation or vibration imparted to such straw in its travel over the corrugated bars and the fingers of such upper conveying system. The described construction of the conveyers and fingers of the upper conveyer system permits the grain to pass freely to the intermediate second conveyer of the machine, and this second conveyer is adapted to travel in a reverse direction to the line of travel of the straw under the influence of the members of the upper conveyer system. Said upper shaking-separator and conveyer system operates to carry the straw and chafi from the threshing-cylinder rearwardly to the delivery end of the machine, but the second intermediate conveyer travels from rear to front of the machine for the purpose of conveying the grain loosened by and deposited from the upper shaking-separator and conveyer system onto the second or intermediate conveyer back to the third or lower shaking-separator and conveyer system and into the path of the blast of air from the primary fan of the machine.

The second or intermediate conveyer 50 lies immediately below and in close relation to the conveyers 18 27 and the finger-shaft of the upper conveyer system,and said second or intermediate conveyer 50 extends continu ously from the rear end of the machine to a point in advance of the slotted rear end 9 of the straw'board or rack 7. Said second or intermediate conveyer 50 consists of endless belts or chains and a series of cross-slats 56, provided with the teeth 57, and said conveyer 50 operates in connection with a fixed grainboard 58, which conforms to the longitudinal contour of the conveyer 50 and is suitably supported within the main frame or casing 1 to receive the grain as it drops through the members of the upper conveyer system. The front end of the long intermediate second conveyer 50 passes around and is sustained by a roller 51 on the driving-shaft 51, While the rear end of said endless intermediate second conveyer is supported by an idler-roller 54.

The front driving-shaft 51 is j ournaled in suit able bearings 52, attached to the main frame or casing below the slotted delivery end of the strawboard 7, and to one end of this shaft 51 is attached a driving-pulley 54. The rearidlerroller and shaft are supported in bearings 55 on the machine-frame 1 at the delivery end thereof, and the long second conveyer 50 is sustained at intervals throughout its length bya series of idler-rolls for the purpose of keeping the conveyer belts or chains taut and in proper relation to the grain-board 58. One of these intermediate idler-rollers is indicated at 59 to lie in the plane of the grain-board 58, said roller 59 being journaled in suitable bearings on the main frame and working in a slot or opening in the grain-board 58. Another idler-roller 61 is journaled in bearings 62 on the main frame at a point adjacent to the driving roller and shaft 51, and other idler-rollers 63 are likewise journaled in bearings on the main frame to engage with the chains or belts of the conveyer 50 at a point adjacent to the roller 59 and to properly direct the conveyer to pass beneath said roller 1 59 and out of the path of the toothed bars on the lower vibrating conveyer 65. This vibratin g separator and conveyer 65 is the third or final conveyer arranged longitudinally in the machine in accordance with myinvention, and said conveyor 65 is arranged beneath a part of the grain-board 58 and the front part of the endless second or intermediate conveyer 50. The vibratinglower separator and con-' veyer 65 is arranged in an inclined position longitudinally within the machine and its lower front end lies below the slotted delivery end of the vibrating straw board or rack 7, While the rear delivery end of said separator and conveyer 65 is arranged to overhang the recipro eating shoe. This lower inclined vibrating separator and conveyor 65 consists of a frame 65, a series of cross-slats 72, and a series of longitudinal corrugated bars or rods 73. The cross-slats 72 are attached rigidly to the frame 65, and they are spaced at suitable distances from each other to permit the grain to pass through the same onto the lower vibrating grain-board 75, and the bars or rods 73, forming a part of said lower vibrating conveyer 65, are attached rigidly to the end rails of the frame 65 and to the cross-slats 72. The longitudinal rods or bars 73 are corrugated to present the roughened or irregular working surface for the lodgment of any straw or chaff which may pass from the uppershakingseparator and conveyer system and be carried back by the intermediate conveyer 50. As this frame 65 of the lower conveyer is positively vibrated by suitable connections with the machine, the straw and chaff are subjected to a violent agitation as they travel over the working surface of the conveyer 65.

It will be observed that the idler-roller 61 for the intermediate second conveyer is arranged close to the working surface of the lower vibrating conveyer 65, and as the lower strands of the endless belts or chains of the second conveyer 50 are driven in a direction from front to rear of the machine the toothed bars or slats of said conveyer 50 are caused to coact with the vibrating conveyer 65 to carry the straw and chaff rearwardly through the machine. The lower vibrating separator and conveyer 65 is suspended in the machinecasing to enable said separator and conveyer to reciprocate or vibrate therein, and the front end of said conveyer-frame 65 is connected with a cranked rock-shaft 66, journaled in bearings 67 on the frame 1, said rock-shaft 66 having the arms 68, to which are connected links or pitmen that lead to the shaft of the primary fan or blower, presently referred to. The rear end of the frame 65, forming a part of the vibrating separator and conveyer 65, is hung by means of a cranked rock-shaft 69, which is journaled in bearings 70, suitably attached to the delivery end of said separator and conveyer 65, and has its arms 71 journaled in the bearings on the frame or casing 1.

Below the vibrating separator and conveyer 65, which receives and detains the straw and chaff that may pass to the lower part of the threshing-machine, is arranged the inclined vibrating grain board 75. This inclined grain-board 75 is hung or suspended within the machine frame or casing to partake of the inclination of the lower vibrating separator and conveyer 65, and said vibrating grain-board 75 is adapted to receive the grain which may pass through the separator and conveyer 65 and deliver said grain to tho cleaning-shoe. Said grain-board 75 is con-' structed with a series of triangular slats 76, which are fastened to a suitable frame in close relation to or in actual contact with each other, and said slats impart to the main board a step-shaped working surface adapted to receive and retain the grain which may be deposited thereon. The front end of the vibrating grain-board 75 is hung or suspended by means of a crank-shaft 77, connected to the frame of said grain-board and having its arms 78 journaled in bearings 79 at the lower sill of the frame or casing 1, and the rear end of the said vibrating grain-board 75 is suspended by the shaft 80, having its cranks 81 journaled in the bearings 82.

The primary fan or blast-fan is indicated at 83, and it is arranged beneath the straw board or rack 7 and in advance of the lower separator and conveyer 65 and the grain-board 75. The shaft 84 of this primary fan is journaledin suitable hearings on the main frame, and one end of this shaft is extended beyond the machine-casing to receive a double pulley 85, one member of which receives a belt 86, that extends to and around the pulley 6 on the beater-shaft 6, whereby the rotary heater 6 is operated by belt connections with the primary fan.

The shaft 14, that operates to vibrate the straw board or rack 7, is provided on the side of the machine adjacent to the pulleys 2 with a double pulley S7, and from one member of-this double pulley 87 extends a belt 88, which runs to the member of the pulley to rotate the fan and its shaft, thus causing the shaft to be positively driven from the shaft 14, that operates the straw board or rack 7.

The lower vibrating separator and conveyer 65 of the machine is driven by connections with the shaft of the primary fan, and to this end I provide the fan-shaft 84; with the eccentrics 89, that receive the yokes of the pitmen 90,which have their other ends attached to the crank-arms G8 on the rock-shaft 66, that sustains the front end of the lower vibrating separator and conveyer 65. It will thus be seen that the fan-shaft of the primary fan is driven from the shaft that operates the straw board or rack and that said fan-shaft in turn drives the rotary heater and imparts the vibrating motion to the lower separator and con veyer 65.

The lower grain-board 7 5 is driven by means of a counter-shaft 91, which is journaled in hearings on the machine-frame between the front and rear shafts that sustain said grainboard within the machine, and this countershaft 91 is provided with cranks 91, to which are attached links or rods that lead to the front end of the grain-board 75, thus operatively connecting the board with the countershaft for driving said grain-board as required.

One end of this counter-shaft 91 is equipped with a large pulley 92 and with a smaller pulley 93, and the other end of said countershaft 91 has a large pulley 108 attached thereto for a purpose which will presently appear.

The shaft of the threshing-cylinder is provided at its end opposite to the driving-pulley with a pulley 94, that propels a long belt 95 to drive the pulley 92 on the counter-shaft 91, the pulley 53 of the shaft that propels the long intermediate conveyer 50, and the pulley 15 of the shaft 14 that vibrates the straw board or rack 7. By reference to Fig. 2 it will be seen that this long belt 95 passes directly to and around the pulley 94 to the pulley 92, thence over the pulley 53, thence under the pulley 15, and back to the pulley 94-, whereby the several shafts are positively driven by a single belt connection with the threshing-cylinder.

The cleaning-shoe of my machine is indicated at 96, and in the embodiment of this shoe itis arranged to partake of a reciprocating movement or play in a horizontal plane lengthwise of the machine in contradistinction' to a transverse vibrating movement or play ordinarily given to the shoes of threshing-machines. This cleaning-shoe comprises a suitable frame or casing and a series of sieves or riddles 97, and said frame orcasing of the shoe is'supported and guided within the machinecasing by means of slotted bars 98. These slotted bars or rails are fixed to the casing or frame 1 in horizontal positions and upon the sides of the same, and said bars or rails have the longitudinal slots 99 to receive the guidearms 100, which are attached rigidly to the frame or casing of said cleaning-shoe. I preferably employ guide-arms arranged in pairs on opposite sides of the shoe casing or frame, and each pair of arms are joined together by means of the rails 101, which are fixed in a suitable way to the arms 100. The guidearms 100 are loosely fittedin the slotted guide bars or rails to support the cleaning-shoe within the main frame or casing 1 and to direct said shoe in a horizontal path when it is vibrated. To the connecting-rails 101 of the cleaning-shoe are pivotally attached the rear ends of the pitmen 102, which lead to and are fitted on the eccentrics 103 on the shaft 10% of the shoe-fan 105. The cleaning-shoe is arranged in the frame orcasing at the delivery end thereof and below the conveyer 27 and finger-shaft 40 of the upper conveyer system, and to this cleaning-shoe is arranged to deliver the rear end of the vibrating grainboard 75. The shoe-fan 105 is arranged in advance of the shoe 90 to deliver its blast directly to the sieves or riddles therein, and to one end of this fan-shaft 104: is attached a pulley 106, that receives the-belt 107, driven from the member 93 of the double pulley on the counter-shaft 91. It will thus be seen that the fan-shaft is belted directly to the counter-shaft to be rotated or driven thereby, and said fan-shaft is operatively connected by the pitman to the reciprocating shoe to actuate the latter.

The pulley 108, which is attached to one end of the counter-shaft 91, is connected by a belt 109 to the pulley 36 on the drivingshaft 19 of the front shaking separator and conveyer 18, forming a part of the upper conveyer system, and this shaft 19 operates through the pulleys 37 and 38 and the belt 39 to drive the shaft of the rear conveyer 2 In connection with the series of fingers 26 at the delivery end of the straw board or rack 7 I employ a toothed deflector-cylinder 110, arranged to beat the straw and chaff as they pass from the straw-rack to the front conveyer 18, and said deflecting-cylinder is operatively connected with one of the shafts of the machine to be rotated or driven positively thereby. The deflecting-cylinder 110 is ar ranged immediately above the series of fingers 26, and it is provided with a series of teeth 110, which are suitably fastened to blades or wings on said deflecting-cylinder. This cylinder 110 has its shaft 111 journaled in bearings on the frame 1, and one end of said shaft has a pulley 112, around which passes a cross-belt 112, that extends to and around the pulley 87 on the shaft 14: that drives the straw rack or board 7. The cleaned grain from the final riddle or sieve of the reciprocating cleaning-shoe 96 is delivered into a trough 113, arranged on the frame or casing 1 .belowsaid final sieve of the shoe, and in this trough operates a screw conveyer 114, the shaft of which is provided at one end with a pulley 115,'thatis drivenby a belt 116 from a member of the double pulley IIC ' rear of the shoe 96, and in this return-trough operates a screw conveyer 118, that delivers to the belt-elevator117, one end of the screw conveyer-shaft being fitted operatively to the elevator-belt to be driven thereby. The return-elevator 117 is arranged on the outside of the machine-casing 1 to extend from the return-conveyer 118 to a suitable point adjacent to the threshing-cylinder, and from this return-elevator leads a spout or chute which conducts the tailings back to the cylinder in an ordinary manner familiar to those skilled in the art. The upper shaft 120 of the return-elevator has a pulley 121,Which is driven by abelt 121, that passes around a pulley 122 on the shaft 14, said pulley 122 being adjacent to the pulley 15, that is driven by the belt 95.

In connection with the vibrating lower separator and conveyer of the machine I employ a stationary straw-rack 123, which is supported within the machine-casing over the cleaning-shoe 96. The stationary strawrack 123 has its frame attached to the main frame in a suitable manner, and said strawrack has two series of bars 125 126, which are rigidly fastened to the frame of said strawrack. The upper series of bars 125 are arranged in alternate relation to the lower series of bars 126 of said rack, and said bars are adapted to receive the straw and chaff which are delivered from the conveyers 65 50. The straw deposited on the conveyer 65 is carried along the same by the vibrating motion imparted thereto in the manner described and by the action of the lower strand of the conveyer 50, and said straw-rack 123 is in line with the delivery end of the lower separator and conveyer 65, so that it occupies a parallel position with relation to the lower side of the conveyer 50, whereby the toothed bars on said conveyer 50 are adapted to carry the straw along the rack 123, over the cleaningshoe 96, and thereby deliver the straw to the stacker.

The stacker is indicated at 127, and it is suitably supported on the delivery end of the threshing-machine. This stacker is of ordinary construction familiar to those skilled in the art and it is designed to be driven by power connections with the rear shafts of the threshing-machine.

To prevent the straw and chaff which may pass through the slotted delivery end of the straw-rack 7 and the front end of the intermediate conveyer 50 from passing to the fan 83 I provide a series of deflectingfingers 128, which are attached to a cross-rail 129, suitably fixcd to the main frame below the strawrack 7. These detaining-fingers 128 are arranged in inclined positions downwardly and 'rearwardly with relation to the primary fan 83 and said fingers serve to deflect the straw or chaff which may be deposited thereon onto the lower separator and conveyer 65 of the machine.

This being the construction of myimproved machine, the operation may be described as follows: The threshing-cylinder is driven by a suitable belt from a traction-engine or other source of power, and from the pulley 94 on the threshing-cylinder shaft is driven the counter-shaft 91,which in connection with the described gearing or belt connections, operates all the working elements of the machine. The straw-rack 7, the conveyers 18 27, and the finger-shaft are moved to carry the straw and chaff from the cylinder to the delivery end of the machine; but the intermediate conveyer 50 is driven in a direction to travel from rear to front, thus impelling said conveyer 50 in a reverse direction to, the line of travel of the members of the upper shakingseparator and conveyer system. The lower separator and conveyer 65 on the vibrating grain-board is driven to convey the straw and chaff and the grain respectively from front to rear of the machine, and the lower grain-board 75 delivers the grain to the reciprocating shoe 06, while the lower strand of the conveyer 50 operates to carry the straw along said conveyer 65 and the straw-rack 123 to deliver the latter to the stacker. As the straw passes over the straw rack or board 7, the conveyers 18 27, and the rocking fingershaft the straw is agitated and the grain loosened therefrom. The loosened grain flows through the slots or openings in the straw board or rack 7, the conveyers, and the fingershaft upon the grain-board 58, and any grain deposited on said grain-board is swept or carried by the conveyer 50 from rear to front of the machine and delivered upon the lower separator and conveyer 65 and the vibrating grain-board 75. As the grain passes from the slotted part of the straw-rack and the conveyer 50 it is subjected to the blast of air from the primary winnower or fan, and the lower separator and conveyer 65 operates to detain the major portion of the fine straws or chaff, while the grain passes through said separator and conveyer 65 and lodges upon the grain-board 75. As before described, the fine straws and chaff on the separator and conveyer 65 are carried by the conveyer 50 across the straw-rack and to the stacker, while the grain from the board 75 is delivered directly to the cleaning-shoe 96. In this shoe the grain is subjected to the action of the riddles or sieves and exposed to the blast of air from the shoe-fan 105. The fine straw and chaif are blown by the fan from the shoe out through the rear end of the machine, the cleaned grain is delivered to the trough 113, while the tailings are delivered from said shoe intothe return-trough 119, to be delivered to the return-elevator 117, which carries the tailin gs back to the threshing-cylinder.

In the detail view, Fig. 11, and in Fig. t I have shown the straw-rack provided with a series of forwardly-projecting fingers 130, which are adapted to project over the rear delivery end of the lower vibrating conveyer to insure the passage of straw across the space between the lower conveyer and the'strawrack 123, andat its rear end said rack 123 is also provided with the projecting fingers 131 (see Fig. 8) to insure the delivery of the straw to the stacker. The rear delivery end of the vibrating grain-board '75 is provided with the series of rearwardly-projecting fingers 132, adapted to the passage of straw and chaff to the riddles of the cleaning-shoe on the forward movement of the grain -board. (See Fig. 11.)
